I would be interested to know the maker of the speaker that contains the same combination of design features as PMC? PMC speakers are expensive so there might be an alternative at a lower price that I am not aware of.

That is not something I can tell you off the top of my head without doing research. Especially that you are asking me to come up with the same speaker for less money. Some of the ones like Meadowlark have went out of business years ago.

Transmission line speakers were never as popular as other designs. For the most part, passive radiators are nearly as effective and a much more time and cost efficient way to do things for manufacturers.

PMC does it their way and charge the customer appropriately for time and materials. You pay for that.

Now, think about why a "transmission line speaker" may not be very popular anymore?

Allow me to explain... The bass waves will travel through the transmission lines, get delayed by a great deal of time.

Now, these days, we know how important "timing" is in speakers with all the drivers time and phase aligned down to the last picosecond... Especially adjustable speakers like Wilson. It is important for the overall coherence of sound.

Does PMC get around it? I'm sure they have it figured out but without having heard them, I can't comment.

If you have a technical explanation how the transmission line delay of lower octaves is accomplished, I would be curious to hear about their solution.

Many of the DIY projects have the transmission line designs to be used with exotic and high efficiency drivers that many manufacturers do not necessarily want to deal with as they are "specialty speakers".

So you are not going to see many these days.

The important thing is that if they sound good to your ears and you are enjoying music, that's all that matters. I have no reason to doubt PMC is a great speaker but have zero experience with them.

Here is Paul McGowan's take on transmission line speakers. https://youtu.be/QisuofWF4Zk

PMC transmission line speakeres are different from others becaused of the special absorbing material that is used to line the tapered transmission line. This causes mid and upper bass frequencies to be absorbed while allowing low bass frequencies to exit the vent in phase with the main bass driver.

Here is one article that helps to explain the concept.

There you go then. So if PMC is pushing forward with their philosopophy and the way they want to accomplish things while attracting audiophiles, then the model is a success. Again, the most important thing is for you to be happy since you are the one listening to them.

Pictures of your setup would be nice

I just love those soft dome midrange units and how they implemented the transmission line.

Thank you gem666

Pictures yes, let me figure out how to post one.

I never though that i would fall i love with a “big baffled”

Is definitely a seious contender to anybody looking for
A middle ground of the “ying and yang” spectrum. One
End gives you the magico, yg etc. While the other end
Gives you harbeth, spendor and other bbc inspires
Design.

I just hope there’s no incoming new model since this present
Model is 8 years old already.

Especially wilson wins, but if you want musicality like just concentrating

The music— pmci mb2 se is off the chart!

I am so enarmored with this speakers that i no longer gets distracted
And just listen and just let my guard down enjoying. No more
Analizing!

I dont feel like i downgraded at all since both ex are much more
Expensive, infact i feel like my enjoyment is a level or two up.

Thank you pmc!!!!

To fellow pmc owners—what brand of cables do you use?

Thank you

Elmer

Welcome to PMC MB2SE Ownership Elmer. As an owner I’m keen to know what amplifier you are powering them with? I use specialized speaker cables from TimePortal. 8 AWG shielded silver coated copper.
